SKYLIGHT.

SPECIFICATION forming part of Letters Patent No. 416,445, dated December 3, 1889.

Application filed MayllO, 1889. Serial No. 310,356. (No model.) i

To all whom t may concern:

Be it known that I, FREDERICK S. CorLEY, of Stapleton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Skylights and Glazed Roofs; I and do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

Figure 1 is a transverse section of Iny improved longitudinallychanneled sash-bar and of the plates of glass resting thereon. Figs. 2,3, and 4 are similar sections illustrating, respectively, modifications in the form of the bar; and Fig. 5 is a view in perspective of a glass-covered roof or skylight supported upon the improved sasl1-bars, showing the inclination thereof.

This invention relates to the bars for supporting the plates of glass in a skylight or glass roof, and has for its object to provide at a low costa simple efficient support for the glass, which shall serve to collect and conduct away the moisture resulting from condensation thereon, or from a leakage through the joints between the plates.

It consists in a supporting-bar constructed of sheet metal longitudinally folded to form a longitudinal gutterwith re-enforced sides, and in devices for retaining the same in position, substantially as hereinafter described and claimed.

In the accompanying drawings, AA A represent the plates of glass for a skylight or glazed roof, and G G the improved supporting bars 'or rafters, upon which said. plates are fitted in a sloping position to form the skylight or roof. Eachof said bars or rafters is constructed, in pursuance of my invention, of an extended plate of sheet metal longitudinally folded to form a channeled bar having a central gutter c, and having its sides bent inward and doubled each upon itself, as at d d, so as to re-enforce the same and direct the Water of condensation. The channeled bars G G, of longitudinally-folded metal, are properly supported at their ends, in the customary manner, upon transverse beams or bars E E', Fig. 5, so as to be inclined more or less. Each. bar is fixed with its channel upward in a sloping position, and being thus mounted serves as a conduit which will readily discharge at its lower end any Water falling therein, the sides of the conduit being doubled, so as to afford the greatest possible rigid ity and strength in the length of the bar.

In practice a metallic cap-plate F, of sheet metal, having'its two edges bent longitudinally to embrace the sides of the transverse beam E, by which the lower ends of the bars are upheld, and its upper side transversely inclined at an angle to correspond with the slope of the bars G G, is secured upon said transverse beam, as shown in Fig. 5. The bars G G are kept from slipping longitudinally upon the cap-plate F by means of hooks II, engaging the bars at their lower ends, the upper ends of the hooks being bent over the cap-plate and secured upon its inner side. The spaces between the bars G G, under the lower ends of the glass plates'A A and above.

the cap-plateF on the transverse beam E, are closed'by means of afacing-strip K, notched to embrace the several bars, as shown in Fig. 5. The glass plates A A are tted and secured upon the channeled bars G G to form butt-joints centrally along each bar, so that any leakage at the joint will be caught in the gutter c, formed in the bar.

It is evident that the construction of a laterally-re-enforced channeled bar with a central longitudinal gutter and inwardly-folded sides, as described, admits of various modifications in the form thereof in crosssection.

Fig. 1 illustrates the bar having its central channel or gutter in an angular V-shaped form in cross-section. Fig. 2 shows the saine with the gutter rounded or U -shaped in crosssection. Fig. 3 shows it when made rectangular in cross-section; and Fig. 4 illustrates a modification of the invention in which the gutter is rectangular in cross-section, with its doubled sides folded to form an ornamental outline, as seen in the cross-section of the bar. In either case the sides of the bar are formed of two thicknesses of metal and its upper longitudinal supporting edges are transversely arched, whereby a maximum of strength is obtained in the length of the -channeled bar with a minimum of Weight.

IOO

I elani as my inventionl. A longitndinally-channeled bar f or sk)1- lights and glazed roofs, constructed of an extended strip of sheet metal longitudinally bent to forni a central gutter, and having;` its sides eaeh folded upon itself to re-enforee the bar and forni therein double lateral walls eemposed of four longitudinal webs, substantially in the manner and for the purpose herein set forth.

2. The combination, with the channeled supporting-barili a skylight or sloping` glazed roof and the transverse plate or beam upholding its lower end, of the hook K, engaging the lower end of the bar at one end and bent over said plate or beam al the other, substantially in the manner and for the purpose herein set forth.
